CAMSHAFT

The camshaft is a main driving unit of the valve train. The air inlet cam, the exhaust cam, and the cam
journal are on the shaft. It controls the intake and exhaust valve to open and close at the correct time.
Wear to the camshaft will affect engine performance and cause excessive noise.

CAMSHAFT REMOVAL

• Loosen valve cover bolts and remove cover.
• Remove the cam chain tensional bolt cap, and remove the O-ring.
• Tighten the cam chain tensioner by adjusting bolt clockwise.
• Turn the flywheel counterclockwise to make the " T" mark on the
flywheel align with the mark on the crankcase. When the hole on
the cam chain (timing drive chain wheel) is up, it should be at the
